GONVEYER-BUCKET.

Specification of Letters Patent.

Patented Aug. 8, 1916.

Application filed June 2 5, 1914. Serial No. 847,256.

To all whom it may concern:

Be it known that I, CHARLES H. RUTH, a citizen of the United States, residing at Brawley, in the county of Imperial, State of California, have invented certain new and useful Improvements in conveyer-Buckets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the type of excavating machines described in my application for patent filed July 28, 1913, S. N. 781,616.

The object of the invention is to improve the construction of the conveyer buckets.

A further object of the invention is to so form the buckets that a maximumv amount of space will be available.

A still further object of the invention is to provide the buckets with hinged doors locked in such positions as to not interfere with the entrance of the material intothe bucket.

A still further object of the invention is to so construct the doors that they will swing about their pivots to eject the material from the buckets.

With these and other objects in View, such as will appear as the description progresses my invention comprises the combination and arrangement of parts as herein set forth and subsequently claimed.-

Referring to the drawing: Figure 1 is a sectional View, showing a plurality of buckets attached to a conveyer chain. Fig. 2 is a front elevation of one of the buckets. Fig. 3 is a rear elevation thereof. Fig. 4 is a plan view. Fig. 5 is a perspective view of the door detached. Fig. 6 is a transverse sectional view.

Referring to the drawing by reference characters wherein like parts are indicated by like characters throughout the several views: the buckets which are indicated generally by the reference character 1 are attached to the conveyer chains 2 in a manner similar to the attachment of the buckets to the conveyer chains in the above mentioned application and cooperate with the machine in said application ina similar manner.

The bucket 1 comprises a rectangular body portion 2', said portion being open at 1ts front, rear and uppersides and hav ng downwardly inclined rear edges 3 whlch terminate a short distance above the plane of the bottom 4. The rear portion 5 of this bottom is bent upwardly at an angle to the said bottom and is formed into a flange 6 which is disposed vertically between the sides of the body portion. This flange acts as a stop for the door.

The sides of the bucket 1 are provided with. ears 6' which are bent at right angles to the sides and engage the flange 6 so that the flange will be braced. This will prevent the bending of the flange 6 into its original position or into the plane of the rear portion 5 upon the successive operations of the door 8. Extending transversely across the bucket between the sides thereof and pivotally supported at 7 is a door 8 which closes the rear opening in the bucket normally. Secured to this door and extending at right angles thereto is an ear 9 having a flange 10 thereon extending upwardly and rearwardly from the upper edge of the door 8 and at right angles to the plane of the ear, by means of which the door is operated as will later appear to eject the material from the bucket.

A pin 11 is secured to. one wall of the bucket and projects inwardly adjacent the upper end of the door so that when the door is swung forwardly a predetermined distance, the edge of the said door will contact with the said pin to limit the movement of the door.

The bucket is secured to the chains 2 by ears 13 pivoted to the chains at the forward end of the bucket and by links 14 pivoted to the rear inclined edges of the bucket and to the chains 2. When the bucket is in the position marked A in the drawing the said bucket is being filled with material by scooping the same and by using the particular form of bucket I have just described, the material is allowed to enter the opening in the front of the bucket and the opening at the top of the bucket, and when the bucket assumes a position marked B the ear 9 contacts with the edge of the plate 15 so that further movement of the conveyer chains 2 will cause the door/to be oscillated about its pivot so as to eject the material from the openings at the top and at the front of the bucket. j

From the foregoing description it may be seen that I have provided a bucket for use on conveyers of; such character that the ma.-

terial being lifted by the same will enter the of the bottom of the bucket being bent upwardly and having an angnlarly disposed flange at the upper edge thereof, a door pivotally mounted in the bucket at its upper end and so arranged that its lower end will contact with the flange to limit its move ment in one direction, an elongated ear secured to the door and extending at right angles thereto and at right angles to its line of pivot so as to brace the door, the said car being in contact and secured to the door throughout its entire extent and having an upwardly extending portion adapted to be engaged by a suitable member to swing the door forwardly and means for limiting the forward movement of the door.

In testimony whereof, I afiix my signature, in the presence of two Witnesses.

CHARLES H. RUTH.
